-Pyroscope for Python
-====================
+Pyroscope Python Integration --Beta--
+=====================================
 
-build
+**note**: This is a beta release. It requires local compilation, might be
+buggy and is frequently updated. For the initial implementation, find it [here](https://github.com/pyroscope-io/pyroscope-python). Please report any [issues](https://github.com/pyroscope-io/pyroscope-rs/issues).
+
+## Installation
+
+1. You need the Rust toolchain to compile the library locally. To install
+   Rust:
+
+```
+curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain stable -y 
+export PATH=$PATH:/root/.cargo/bin
+```
+
+2. libunwind8-dev is also required. For Ubuntu:
 
 ```
-python -m build
+apt-get install -y libunwind8-dev 
 ```
 
-upload
+3. Building/Insalling from PyPi package
+
+```
+pip install pyroscope_beta
+```
+
+4. Building/Installing from source
+
+Change directory to `pyroscope_ffi/python` and run
+
+```
+make install
+```
+
+## Configuration
+
+Configuration is similar to the old package except for `application_name`:
+
+```
+import pyroscope_beta
+
+pyroscope_beta.configure(
+  application_name       = "python.app",
+  server_address         = "http://localhost:4040",
+
+  tags = {
+    "key": "value",
+  }
+)
+```
+
+## Adding tags
+
+Tags passed to configure are global. To tag code locally, you can use:
 
 ```
-twine upload dist/*
+with pyroscope_beta.tag_wrapper({ "profile": "profile-1" }):
+    // Tagged profile
 ```
